The module includes its own CPU and 4K-word dual-port memory, and it uses a 9-pin D-shell connector for high-speed rack-to-rack communications plus a 25-pin MONITOR RS-232 serial port for local status and self-test. In an AutoMax rack, a complete network drop must include a Power Supply, a Processor, and a Network Communications Module, with the master at drop 0 and subsystems at drops 1–55.
